1、ANSI INCITS 297-1997 (R2002) (formerly ANSI X3.297-1997) for Information Technology Fibre Channel Physical and Signalling Interface-2 (FC-PH-2) American National Standard Approval of an American National Standard requires review by ANSI that the requirements for due process, consensus, and other cri
2、teria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but n
3、ot necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclude anyone, whether he has approved the
4、standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interpretation of any American National Standard. Moreov
5、er, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose name appears on the title page of this standard.

CAUTION: The developers of this standard have requested that holders of patents that may be required for the implementation of the standard disclose such patents to the publisher. However, neither the deve

As of the date of publication of this standard and following calls for the identification of patents that may be required for the implementation of the standard, no such c
9、laims have been made. No further patent search is conducted by the developer or publisher in respect to any standard it processes.
